M flares, G2 geomagnetic storm watch
Our Sun has been moderately active the past few days! Sunspot region 2824 produced numerous C-class events and three M-class solar flares during the past few days. An M1.4 solar flare on Saturday, 22 May was the strongest solar flare it produced. A couple of these C and M-class solar flares were eruptive and produced coronal mass ejections which could have an earth-directed component.
